[dpdk-dev,v2,3/8] devargs: introduce insert function
Checks
Commit Message
This new function expects a fully-formed rte_devargs, previously parsed
and allocated.
It does not check whether the new rte_devargs is compatible with current
bus configuration, but will replace any eventual existing one for the same
device.

Please explain why this function is needed.
